FASTENING FOR M'EETING-RAILS'OF SASHES.

SPECIFICATION forming part of Letters Patent No. 292,202, dated January 22,1884.

Application filed October 15, 1883. Model) jects of my invention are to render the con-v struction simple and inexpensive, and especially to provide more convenient and better operating devices for limiting the movement of the sweep. I attain these objects by the simple construction illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my sash-fastener. Fig. 2 is a plan view of the base-plate thereof. Fig. 8 is a reverse plan View of the main portion of the sweep. Fig. 4 is a plan view of the latch-lever. Fig. 5 is a vertical section, partly in elevation, of my sash-fastener on line or m of Fig. 1; and Fig. 6 is a vertical section thereof on a line extending longitudinally through the middle of the sweep. I Heretofore sash-locks of this class have generally been provided with a stop-pin on the under side of the sweep which worked in a curved slot in the base-plate, and with other and separate means for locking the latch-lever to the base-plate.

Instead of the foregoing construction, I make asingle stud or projection on the base-plate do the double duty of limiting the movement of the sweep and oflocking the latch-lever thereto when in both of its different positions-that is, when locked' and unlockedp The keeper A and the end def the sweep B, which engages-said keeper, may be of any'ordinary construction. As in many other fasteners of this class, the sweep has a chambered hub, through which the pivotal post C passes to secure it to the base-plate D. I provide the inside of this hub with two stop l ugs, b b, as

shown most clearly in Fig. 3. Said hub is also slotted in front, ,as at c/Fig. 3, to allow the latch-lever E to extend into the hub. I provide the base-plate'D with a single upwardly-projecting lug, (1, Figs. 2 and 5. The outer end of the latch-lever E is in the form of a handle, while the inner end of said lever is broadened, as shown most. clearly in Fig. 4, and perforated to admit the pivotal post C, so that when in place said post holdsthe lever E within the sweep, and also pivots the latch-lever, so that it swings horizontally on a common center with the sweep. (See Fig. 6.) A spring, 9, Fig. 6, bears upon the latchlever with a constant tendency to force said lever downward. The lug d is short enough in height to permit the latch-lever E, when its handle end is raised; to pass over said lug..

Suppose the sweep to have been carried around far enough to bring the latch-lever to the front and then allowed to rest. The body of said lever will fall down by that side or end of the lug d on the base-plate D which is nearest the front, while one of the lugs b on the inside of the chamber of the sweep B will be in contact with the opposite end or side ofsaid lug, thereby locking the sweep firmly in place against movement in either direction until the lever is raised far enough to allow itto be moved over the top of the lug d. The sweep can then be moved in a direction to carry the handle end of E toward the right until the other one of the lugs 12 engages the front end of the lug d, while-the body of the latch-lever E falls down over the rear end of said lug 01, so that the sweepis again locked firmly to the base-plate, but thistime in the position where the sashes are unlocked. By raising the lever and reversing the movement of the sweep it will be stopped in the position where it e11 gages the keeper and locks the sashes.

I am aware that sash-fasteners have been before made which consist of a keeper, a sweep having a chambered hub, a latch-lever with its inner end within the hub and depressed by a spring, abase-plate, and apivotal post, and I hereby disclaim the same.

I claim as my invention- The improved sashfastener herein described, consisting of the base-plate having the lug d, the chambered sweep having the stoplugs b b, and the latch-lever E, extending into the chambered sweep, said lever constructed lugs b engages the opposite side of d, substantially as described, and for the purpose specified.
